SPINNING-RING TRAVELER.

SPECIFICATION forming part of Letters Patent No. 778,923, dated January 3, 1905. Application filed June 3, 1897. Serial No. 639,207.

1'0 all whom it may concern:

Be it known thatI, CHARLES E. TROWBRIDGE, of Whitinsville, county of Worcester, State of Massachusettshave invented an Improvement in Spinning-Ring Travelers, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Travelers used on spinning-rings are made of difl erent weights, the weight being adjusted to the particular class or strength of yarn being spun or twisted. These travelers in use, owing to their rapid movements about the race, soon become so worn that they have to be removed and replaced by new travelers, the part of the traveler which wears most rapidly being that in contact with the under side of the inner flange of the race of the ring. These travelers are now commonly made of flattened wire or rod, the cross-section of the wire or rod being more or less, according to the weight desired for the traveler, said travelers being of uniform cross-section from one to the other end. Inasmuch as these travelers wear only Where they contact with the ring-race, I have devised a new shape of traveler, it presenting a greater cross-sectional area at the point where the traveler is subjected to the greatest wear, and by putting the greater weight of the traveler at this point of greater cross-section it is possible to get more metal in the line of Wear, so that thelife of the traveler may be greatly increased. To effect this, I have devised atraveler which presents centrally a narrow neck which in crosssection is smaller than the end of the traveler, it containingalarger quantity of metal, being heavier and capable of resisting wear for a longer period, and yet the weight of the traveler as a traveler may be regulated as desired.

Figure 1 shows a ring with a traveler upon it, embodying my invention. Fig. 2 shows,

detached, the traveler of Fig. 1; and Fig. 3 represents modified forms of travelers embodying my invention.

The ring A, it having a like race a at each end, is and may be of usual construction.

My improved traveler (shown mounted upon the race in Fig. 1) presents a narrow neck I), both ends Z) 6 of the traveler (see Figs. 1 and 2, where the traveler is shown detached) containing more metal than the neck and presenting a largerarea of metal in cross-section, said increased quantity of metal determining in a great measure the weight of the traveler and presenting more metal to contact with the race of the ring, so that said metal will last longer before it will be worn away, thus increasing the life of the traveler. In Fig. 2 I have also shown the end Z) increased in thickness to thus augment its weight. In Fig. 3 the outer end 6 of the traveler is yet further thickened.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is

A spinning-ring traveler having two end engaging portions of like and uniform width for engaging with the inner and outer sides of a spinning-ring, one of the said end engaging portions being weighted by thickening the metal thereof and both ends widened to present an increased bearing, and a neck of uniform and reduced size connecting the similar end engaging portions, said neck adapted to have the yarn loosely passed beneath the same, to guide the yarn, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
